Blessing in Disguise

I always wondered why people say that something is a "blessing in disguise". If it is a blessing, why does it need to be disguised. Why can't it just be straightforward . A blessing. Nothing more, nothing less. Something good that happened for a reason. After thinking about it, I realized that a blessing in disguise, is our way of turning lemons into lemonade. Take a bad situation and turn it around. Find the good in what would otherwise seem bad. Make it into a blessing. Look at a scenario from all sides and try to see a more positive perspective. It shows us that hope always prevails and that if we think hard enough we can rationalize most things into a blessing.
